|Patch needs improvement:
The get_admin_log template tag defined in django.contrib.admin returns nothing if no user is specified. Although there are currently no cases in admin where this tag is called without specifying a user, the usage comments for the template tag indicate that this should be supported, and this would be useful for other apps using the tag.
Patch is attached.
